Abstract
Objective To study the relation of cerebral aneurysms on communicating branches to the hemodynamic changes of Willis' circle.Materials and Methods Cerebral DSA findings in 199 cases were retrospectively analyzed.Results A 1 dominant signs in aneurysms group of the anterior communicating artery was more common than in control group. In aneurysms on the junction of internal carotid and posterior communicating artery, no difference was seen between aneurysms getting blood supply from basilar artery and those getting blood supply from other artery.Conclusion The development of cerebral aneurysms on anterior communicating segment is related with the hemodynamic changes of the anterior circle of Willis, while hemodynamic changes of the posterior circle of Willis has no relation to the aneurysms on the ipsilateral internal carotid posterior communicating artery junction.
